This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 136.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

Foreword
This document (prEN 958:2012) has been prepared by Technical Committee CEN/TC 136 “Sports,
playground and other recreational facilities and equipment”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 958:2006+A1:2010.
Compared to the previous edition EN 958:2006+A1:2010 the following technical changes have been made:
a) in the scope, energy absorbing systems (EAS) according to this document have been limited to users
weighing not less than 50 kg (total weight including the equipment);
b) in 4.2, the maximum braking length was changed to 1 750 mm;
c) in Clauses 6 and 7, the requirement of 50 kg was added.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive 89/686/EEC, see informative Annex ZA, which is an integral part of this
document.

Introduction
The text of this European Standard is based on the former UIAA-Standard N (Union Internationale des
Associations d'Alpinisme), which has been prepared with international participation.
This European Standard is one of a package of standards for mountaineering equipment, see Annex A.
prEN 958:2012 (E)
1 Scope
This European Standard specifies safety requirements and test methods for energy absorbing systems for use
in climbing on a klettersteig (via ferrata) for people weighing not less than 50 kg (total weight including the
equipment).
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 12275, Mountaineering equipment — Connectors — Safety requirements and test methods
EN ISO 139, Textiles — Standard atmospheres for conditioning and testing (ISO 139)
ISO 6487, Road vehicles — Measurement techniques in impact tests — Instrumentation
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
klettersteig
rock climbing route with artificially constructed, permanent belay
Note 1 to entry: In some cases, the term "via ferrata" is used instead of "klettersteig".
3.2
energy absorbing system
device with two or more attachment points, used to reduce the impact force on the anchorage and on an
attached climber during a fall
3.3
braking length
increase in the distance between the two attachment points measured at the end of the braking action
3.4
deployment position
arrangement or positioning of the energy absorbing device such that the energy absorbing systems can come
into correct use in the event of climber fall arrest
4 Safety requirements
4.1 Design
4.1.1 Load bearing connections
All textile load bearing connections shall be designed so that they cannot be altered by the user.
4.1.2 Connectors
If an energy absorbing system is fitted with connectors for attachment to a via ferrata, these connectors shall
be type K connectors according to EN 12275.
prEN 958:2012 (E)
4.1.3 Construction
The energy absorbing system shall be designed so that it cannot be disassembled into its component part,
except for the connectors.
4.1.4 Deployment position
The deployment position of the braking system shall be designed in such a way t
